Wombit

Wombit is a native Mac app that shows what's filling your disk, explains every item in plain language, and clears space safely: Trash first, with Undo and a log.

Who it is for

• Mac users whose disk is nearly full and who want to know what's safe to remove
• Developers whose disks fill with Xcode, Docker, simulators, node_modules and package caches

The problem it solves

macOS lumps much of a full disk into "System Data" and doesn't say what's in it. Finding the big folders is easy; knowing which ones are safe to remove is not. Wombit maps the disk, explains each folder from a rules catalog with sources, and shows a review of exactly what would move before anything does.

Features

• System Data, explained: split into named parts, each with what it is and how safe it is to remove
• Map, sunburst and list views of the whole disk or any folder
• Developer folders it understands: Xcode DerivedData and simulators, Docker, node_modules, the Gradle, Cargo, npm, pip and uv caches, Ollama and LM Studio models
• Trash first: Undo and Put Back work until you empty the Trash. When a tool has its own cleanup command, Wombit runs that instead of deleting its files
• Safe defaults: only items their owner rebuilds by itself start checked; macOS, keychains, iCloud Drive and the Photos and Music libraries are never offered
• What Changed: a daily history of what grew, with alerts when space runs low
• Uninstaller that shows what each app left behind
• System Monitor for CPU, memory, network and power, and a command-line tool
• Private: no file names or paths ever leave your Mac
